AI Technical Summary
Existing vehicle seat airbag systems struggle to effectively protect occupants in various seating postures, particularly when they are relaxed or reclined, as they deploy airbags from one or both sides of the seat, making it difficult to provide adequate restraint.
The airbag device is designed with a lower portion inside the seat frame and an upper portion outside the frame, deploying to restrain the occupant from the waist to the chest using the inner frame as a reaction surface, while the upper portion expands outside the frame to protect the head and shoulders, utilizing the seatbelt's reaction force for stability.
This configuration ensures reliable restraint of the occupant from the waist to the head, stabilizing the deployment shape and providing comprehensive protection regardless of seating posture, especially during side collisions.
